I encountered the exact same problem you did, but I had to stick to an ImageIO interface, which no other library did. Apart from Jack's great answer, I simply patched the existing GIFImageReader class with a few lines of code, and got it marginally working.

Copy this link into PatchedGIFImageReader.java and use as such:

reader = new PatchedGIFImageReader(null);
reader.setInput(ImageIO.createImageInputStream(new FileInputStream(files[i])));
int ub = reader.getNumImages(true);
for (int x=0;x

Be sure to change the package name to whatever you're using.

Unfortunately results may vary, as the patch was a 1 minute bugfix that basically just exits the loop if it goes past the buffer. Some gifs it loads fine, others have a few visual artifacts.

Such is life. If anyone knows a better fix instead of mine, please do tell.
