Can't import small JPG files

Would you be able to attach your mosaic file and a couple of the jpgs you are using to this thread so we can take a look?

Sure. For some reason I can't attach files to this post. Here's a Dropbox link for the Mosaic file, two sizes of JPG, XCF file (from GIMP where I do the images) and a PNG.

I would like to add a JPG to the matrix and not have any bleed.

I had luck dropping the fixture size to 4px and making the layout 50X800. The ratio is slightly strange when you create a pixel matrix but it still worked.

Could you share the screenshot of map and layout or project, please? Do you still have the colour bleeding problem? 

This looks like it was a bad export from GIMP,  one of the developers re-exported it and it worked fine in Mosaic.

Just to follow up on this the only difference between you image the this on is the DPI so maybe you need to play with that on other images.

Thanks! I'll try chaning some settings.

But the pink colour bleed between red and white remains. It can also be seen on the image you provided. Probably should make a new thread for this :)
