can't load .png icon for rollable table

Hi, first time post and first time on roll20 - for some reason i cannot load a .png file for a rollable table that successfully loaded before the last update - also the remove link for the icon doesn't work so i need to delete the entire item to remove it. some .png work fine but that are all from the same zip file linked from The One Ring entry on the wiki, so doubt the .png files are at fault. any ideas?

Hi, I click on load image within the add item section then browse to the image and have tried both opening it and double clicking on it - both result in the image loading with a broken image icon, then the remove link doesn't work some other images seemed to just remaining with the green loading bar for ages, but loaded eventually, some I had to save without image (as they just seemed to be loading infinitely) then go back into the item and load the image a 2nd time, which then worked - but two images still won't load, one of which I already have loaded into a table prior to the upgrade all images are only 1k files thanks

Hi, Thanks for continuing to look into this I've cleared cache etc, but still no joy - the specific .pngs I'm having issue with won't load by dragging onto either the rollable table or just onto the tabletop (other pngs from the set do load onto tabletop...) which would suggest there is something screwy with the png file itself, but i have used one of them successfully before in an earlier rollable table and got them from a link on the roll20 wiki for The One Ring, plus it looks fine, opens in other apps etc... quite strange

I think I've solved it, sort of...the pngs that were not loading were both '1' die faces and their dimensions of the image are really small (smaller than any other of the pngs) 10x20 and 12x19.... I took one of them and just resized it and made the dimensions slightly bigger, which then loaded fine.... is there some lower limit of image size that can't be successfully loaded - possibly something affected by the most recent upgrade?
