Permitted File Size for Thumbnail

    I’ve uploaded an assortment of pictures of different sizes, and have much enjoyed the ability to select the file to be placed in the post as a thumbnail. I have two pictures, however, which do not even give me the choice to insert them as thumbnails. They’re both decently large at 598×359 and 519×808, in fact they’re larger than other pictures WordPress has turned into thumbnails for me.

    Any ideas as to why these two pictures won’t allow me to do so?

    Thanks!

    For anyone with a future problem along these lines, be sure to check and make sure that the file attempting to be turned into a thumbnail using the built-in method; make sure the file is not a .gif but a .jpg – as was my problem. I’m not sure why – possibly because it can’t thumbnail a color indexed file – but .gif files will not work for this.

    No, it can indeed make thumbnails of GIF files. Only reason I can think that it failed for you was that the file was in a format that the PHP image functions could not understand. Perhaps it was just an odd GIF in some way.

    Anyway, you really shouldn’t use GIF. Use JPG for pictures of real stuff, use PNG for things like graphics and other artwork.
