Direct uploads are rejected if the filename looks like the default filename of a screenshot or thumbnail from the Roblox website, which might be why. This is noted on Special:Upload. If that was the issue, you should give the images a descriptive name. If that was not the issue, you could try using Special:Upload and Special:MultipleUpload in different browsers.
