My GIF is not playing

If your GIF file is not playing or looping, it might be because the file is too large. If it’s more than 1080 pixels high or 1920 pixels wide, you’ll need to reduce the size.

There are a number of free, online tools of varying sophistication that you can use.
Here’s a simple one that will do the job:

Here’s a more sophisticated tool with additional functions:
If you have a large (in MB) gif animation your iPoster can take a very long time to load. If so, you can also use this tool to optimize the image to reduce its size. Try a setting of 100%.


Creating nested lists

I want to nest a list inside a list.

1. Start by writing the items in the first list:

2. Select the text:

3. Click the bulleted list button, the list is created:

4. Continue by adding the items that should be nested:

5. Selected the text:

6. Press Tab on the keyboard, this will indent the selected text:

7. Continue the same way if you want further nesting:

If you want to return to the original, unindented list, press Shift+Tab:

My text is not showing properly (or not all) in Preview

Everything looks fine on my template, but when I look at my iPoster in Preview, the text isn’t showing at all, or the formatting is wrong.

This is probably because there was some hidden “junk code” in the document you copied and pasted from and it is preventing your text from displaying as it should. To clean up the code, there are a number of different “fixes”.

Here’s the easiest:

  1. In the template, drag your cursor over the texts that are not displaying to highlight them.
  2. Click on the “Remove Formatting” icon.                                                                                             
  3. Check Preview to see if the text is now displaying. If so, go back to your template and format it as you would like, using the formatting tools in the Content Box Toolbar.

If your text is still not displaying properly, try the following:

  1. If there are images in the textbox, start by deleting them. They are all saved in your Image Gallery, from which you can re-insert them once you’ve fixed the text.
  2. Copy the text. Then delete it from the Content Box.
  3. Paste the text back into the Content Box.
  4. Check Preview. If the text now displays, you can go back to your template editor, format it as you wish, and reinsert the images from your Image Gallery.

Still not looking right?? (You’ve got some really stubborn code hiding in there!) Please do this:

  1. Delete any images, as above.
  2. Copy the text and delete it from the Content Box.
  3. Click on the “Paste as Plain Text” icon in the upper left-hand corner of the Content Box Toolbar.
  4. Paste the text into the field that opens.
  5. Check Preview. If the text displays, proceed as above.

If this still doesn’t work (because you’ve got some really, really mean code blocking things) please do this:

  1. Delete any images as above.
  2. All computers come with a plain text editor, e.g., NotePad on Windows & TextEdit on Mac. Copy-paste all text onto one of those programs.
  3. Delete all texts from your Content Box.
  4. Then copy-paste back onto your iPoster.
  5. Check Preview. If the text displays, proceed as above.

If not, please contact support.

The “DESIGN YOUR iPOSTER” button is missing.

If your don’t see the DESIGN YOUR iPOSTER button at the top of your Main Toolbar, this is because your conference organizer has disabled the function in order to standardize the design of all the iPosters to be presented at your event. They want authors and attendees to focus on content, rather than design.

How do I change Templates?

If you want to change your template, PLEASE READ ALL OF THESE INSTRUCTIONS CAREFULLY, so that you don’t lose any content.

In order to change your template, you click on the DELETE button on your Main toolbar, which will take you back to the Template Chooser page and allow you to select a different template.

All of your images will be saved, and you will find them in the Image Gallery on your new Template.

All of your texts will be deleted, so please do the following:

  1. Copy all of your texts, from all of the Content Boxes and special boxes, and paste them into another document. We recommend a simple text editor.
  2. Once you have copied all of your texts, you can delete the current template and choose another.
  3. Copy and paste your texts back into the appropriate Content Boxes.
  4. To add back your images, place your cursor where you want them inserted and click on the INSERT IMAGES button. Click on the GALLERY Button to choose from your previously uploaded images.

Why Aren’t My Images Larger When I Click On Them In Preview?

When your images are displayed in Preview or on the screens at the conference, they will only be as large as the file you insert.

The full display screen is 1920×1080 pixels. Thus, if you want an image to fill the screen, you must insert an image that is 1920×1080.

If your image is only half the size – 960×540 – it will fill only half the screen.

We recommend that your images are at least 600 pixels wide. However, don’t try to make your image any bigger that the original. This will only cause it to be blurry and hard to read. Try to find an original that is larger.

In this case, bigger is indeed better. The larger your image (photograph, table, diagram) the more detail you can show.

Can I upload a PowerPoint or PDF poster directly to an iPoster?


There is no function for uploading a poster in another format directly to an iPoster.

But there’s good news: many – if not most – of our authors have their source content in other formats like PDF, PowerPoint, Keynote, Word and other documents. They simply pick an iPoster template that works for the way their presentation is organised, and then transfer the content into the iPoster Content Boxes. It can go pretty quickly – just follow this method:

Enter your texts and images separately.


You can copy and paste text from your source, directly into a content box.


All images should be inserted using the Insert Image tool, which you will  find on the toolbar of each content box.

IMPORTANT: Images must be in JPG, PNG or GIF format
. When inserting images, remember that images will expand to their full size when tapped by visitors to your iPoster or by you during your presentation. So, make sure your images are as large as possible – up to 1920 x1080 pixels. And if possible, 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.

Treat diagrams, charts, tables, etc the same way
. 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 iPoster. 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 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
  • include as much content as you feel is necessary to present your research with the detail it deserves. There are no limits to content. As soon as you exceed the apparent physical space of a content box, it will scroll.

One last tip.

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


Be sure to view our tutorials, which will give you a broad overview of the iPoster system.
