Authors of papers accepted by the main conference or a workshop may upload their posters and thumbnails for display on the conference website using the links below
In order to upload a poster for a conference you must have a paper accepted and log into the account which is associated with that paper. Accounts are identified by an email address. Accounts may be created as part of the process of loading papers into the system in which case a new password will need to be requested for a freshly created account.
Posters should be in landscape format. The file must be a PNG format with a maximum dimensions of 5120 x 2880 pixels and be no more than 10 mb in size. Thumbnails must be a PNG file and should be no larger than 320 x 256 pixels and no more than 5 mb.
The Poster Upload page has an option, Scale images to fit, which will scale your upload so that it fits within the limits (exceptionally large images cannot be scaled, see Warning about Decompression Bombs). Using this option will allow images that are larger to be uploaded and rescaled as they are uploaded.
We recommend that you create the thumbnail from a visually interesting image from your paper.
Use a solid background for your posters and thumbnails as opposed to transparent. This works better in the virtual poster spaces.
Note: If you have more than one paper please be sure you upload the correct poster for each paper. The paper title is shown just above the selection area for the Poster png and Thumbnail png. If you have other papers they will be listed farther down on the page and may be selected by clicking on that paper's ID number.
To use the page click on the Choose File option and navigate to the proper png file you wish to upload for both the poster and the thumbnail. If your images are larger than allowed you may select the Scale Images to fit checkbox. Then click Submit.
Posters may take an hour or two to propagate throughout the conference website and may be re-uploaded up until two hours before they are presented at the conference.
You may replace existing uploads with new ones.
These images may appear in virtual poster sessions in GatherTown or Topia. The thumbnails will apppear in the conference's virtual schedule. For main conference papers, they will also appear in the paper browser. It will take up to two hours for the posters to be loaded to GatherTown or Topia after the conference virtual website is open.
Depending on how the workshop is organized it is up to the individual workshop organizer whethers they would like your poster uploaded or not. The workshop organizers are listed at the top of each Workshop page on the conference website.
For conferences without a virtual poster session there is no hard deadline on uploading your poster. If the conference has a virtual poster sessions (e.g. Topia or GatherTown) the deadline is two hours prior to the poster session. However be aware that unforeseen technical issues may always arise and it's highly recommended that you upload your poster at least a day before the poster session.
If no author for your paper is attending the conference uploading of posters is optional (technically it's optional even if you are attending). However, if you do upload a poster and thumbnail these images will be shown to those visiting the website--including after the conference is over and the material becomes available for free.
The most common problem with not seeing ones paper listed on the Poster Uploads page is that the userid (email address) associated with the paper doesn't match the userid (another email address) which you are using to log into the conference website. The papers are usually loaded from OpenReview or CMT or manually input by a Workshop Organizer. For CMT or OpenReview check the email associated with your paper on those sites, otherwise contact the Workshop Organizer about what email was used. Often the best solution is to "merge" the other email address into your desired email address see linked-accounts. You can also log into the conference website using the other email, you may need to reset the password for this other profile if you've never logged in using that email before.
Check for your paper by searching for following the instructions here. If find that you are listed as an author on the paper but don't see it on the Poster Upload page then it is likely that it is associated with another email address. If you cannot figure out what email address is associated with your paper contact help and be sure to include the title of the paper and the author name on the poster page.
In addition to any papers that a workshop organizer is also an author on, workshop organizers see all the papers in their workshop. This is so that the workshop organizer may upload the posters for their papers themselves if so desired and also quickly see the status of papers for their poster sessions.
The only way that posters are identified is if their event type contains the word Poster (but not "Poster Session"). So if the event type is an Oral, or Spotlight, or anything else besides "Poster", then they won't be identified as needing a poster. The way to fix this is to create two different events one with an event type of Oral and one with an event type of Poster. To create duplicate events you can copy and paste the data from one event to another.
If you use CMT or OpenReview Import Wizards: then see import-papers-cmt-or-openreview and check both the Poster and the Oral box when mapping from Accepted papers.
If you use the CMT or OpenReview import to create duplicate Oral/Spotlight and Poster Events but not all the events are Oral/Spotlight kind you can delete the unwanted events.
