How can I add Alternative text to my images?

Alternative text, often shortened to ‘alt text,’ is a short and succinct written description of an image. Well written alt text is important to increase your presentation’s accessibility. Screen readers will read aloud alt text in place of images which means this content will be available to viewers who are blind or low vision.

It’s quick and easy to add alt text to your images on an iPoster. You can add the text in when you first upload the image or you can add it on images that have already been uploaded. Follow the below steps for a guide on how to do this.

For more detailed instructions on how to add images to your iPoste see the following FAQ: How do I add images to my iPoster?

How can I generate subtitles for my videos?

If your conference organizers have chosen to enable subtitles for videos you will be able to generate this using a linked AI. Please note that the AI can take up to 24 hours to generate the subtitles which can then be edited. Make sure that you allow plenty of time to generate captions for your videos and to adjust them as required afterwards.

First you will need to have a video uploaded in either the VIDEO REPOSITORY/GALLERY section, or under the VIDEO PRESENTATION section of your iPoster editor. Both of these buttons are located on the main menu. Please see the following FAQs on how to upload a video into these sections.

These instructions are broken into 2 parts:
  1. Generating subtitles for videos in VIDEO PRESENTATION.
  2. Generating subtitles for videos in VIDEO REPOSITORY/GALLERY

1. Generating subtitles for videos in VIDEO PRESENTATION

1. Upload your video in VIDEO PRESENTATION then click on the green ‘Subtitles’ button

Add a video presentation to your iPoster

There are lots of good reasons to add a video presentation to your iPoster. It’s a particularly great feature to increase the accessibility, reach and engagement of your research. For example, it provides a presentation option for those who cannot attend your conference in-person. Remember that your iPoster will live on and be available on-line long after your conference is over.

It’s also fairly easy to create your own recorded presentation using your computer’s built-in recording functions, or any 3rd party tools like, Zoom, WebX or Microsoft Teams.

A video presentation can provide a general summary of your research or explore a particular theme in more depth. If this option is available for your conference, the ‘Video Presentation’ button will be visible on the Main Menu of your iPoster Editor screen.

Please note that there is a file upload size limit of 100MB. If you need to compress your file you can use a free online service such as:

The iPoster system accepts several video file types for video uploads, including:
  • 3g2
  • 3gp
  • avi
  • flv
  • ts
  • mov
  • mkv
  • mp4
  • mpeg
  • mpd
  • mxf
  • ogv
  • webm
  • wmv

How do I add transcripts for narration or audio snippets?

You have the option of adding transcripts for both narration and audio snippets on your iPoster. First you need to upload a narration or an audio snippet file. You will always be able to add a transcript manually. You may have the option to generate the transcript automatically using an integrated AI component – this option isn’t available on all conferences.

In either case once there is text in the transcript editing box a ‘Transcript’ button will appear on the preview version of your poster. Visitors can then click on this button to read the transcript.

This instruction is broken into two parts:

Part 1: Manually generate a narration or audio snippet transcript
Part 2: Auto generate a narration or audio snippet transcript

Please Note:

You will need to have uploaded an audio file to your poster to be able to follow the below instructions. See the FAQ on adding audio narration to your iPoster if you haven’t done this already.

How do I add images to an iPoster?

Add images to an iPoster in a couple of clicks using the Insert Image tool. You will find this tool on the toolbar of each content box as shown below.

The content box toolbar from the iPoster editor. the insert image tool is circled in blue.

General Image tips

The size of your images is important because it will impact the quality of your overall presentation.  Ensure that your images are as large as possible so that they have maximum impact for the end viewer.  

Images must be in JPG, PNG or GIF format. When inserting images, remember that they will expand to their full size when tapped or clicked on by visitors or by you during your presentation. So, make sure your images are as large as possible – up to 1920 x1080 pixels. And if available, use the original images for best quality. If they are not available, take screen shots of your images, but zoom in before you take them so that, again, they are as large as possible.

As you proceed, save your progress then check your work by clicking on the Preview button. You’ll get a close approximation of how your presentation will look on the HD screens, and can test all of the functionality: content boxes and images expand when clicked, videos play correctly, external links connect, etc…

Slideshow Images

The slide show window (available in some templates) has a minimum image size requirement of  960×360 pixels, but  we recommend that you insert images up to 1920×1080 pixels.

When you look at the slide show in the condensed view any images larger than 960×360 will be cropped. However when you or an end viewer click or tap on the slide show in preview mode or at the conference, it will open up as an overlay and show all images at their full size.

Conference participants will then be able to flick through the slideshow as they wish. Having larger images will provide a more enjoyable and better quality viewing experience for them.

Diagrams, charts and tables

Diagrams, charts, tables, etc need to be inserted as images. Either export them from their source program as JPG or PNG, or take a screen shot. Make them as large as possible, and then import them into your content boxes. That way they will expand to make it easy for your visitors to view them.

Remember that an iPoster can contain so much more than an upload of a  PDF or PowerPoint, so try to take advantage of this by including:

  • Videos
  • Sound files
  • Links to dynamic external information (e.g. online data sets, visualizations, etc…)
  • As much content as you feel is necessary to present your research with the detail it deserves. There are no content limits.  As soon as you exceed the apparent physical space of a content box, it will scroll.

Adding an image to an iPoster content box

1. Either drag and drop your image into the upload box or click on the box to choose an image from your files. If you have previously uploaded images click on the ‘Image Repository’ tab to browse and select an existing image.

Iposter editor tool bar. The insert image tool is circled in red and a red arrow points down to an open dialogue box with the words ' Drop file here to upload or click here to select.'

2. After dropping or selecting your image file allow approx. 10 seconds for it to upload. The Image Info tab will be displayed. You can choose to add captions or alternative text to your image or change the alignment using the options in this box. Click ‘Ok’.

3. The image is now inserted into the content box. You can double click on the image to return to the Image Info tab and change/update any of the settings here.

Accessing uploaded images

All uploaded images will be stored in the Image Repository on the main menu. When you click on the insert image tool you may choose to upload the image (as in the process outlined above) or you can insert an image that has already been uploaded. Simply click on the Image Repository tab to view your stored images.

Image Repository button in the editor circled in red. A red arrow points at the opened dialogue box in the center of the screen which shows the images stored in the repository.

Editing images

Images can be edited to some degree within the iPoster system. From the Image Repository click on the green edit button under the relevant image. You can crop, re-size, rotate, or flip the image using the controls in the top menu. The below example shows the cropping tool. You can also zoom in or out on the image to make it easier to see the edits you’re making.

When you’ve completed your edits you can either save the edited image as a new image or replace the original image with the edited one.

Be sure to view our tutorials, which will give you a broad overview of the how to create your presentations.
