Batch Upload - Large files not recognized

[gtg941f]

I created my custom folder within the /albums/ folder and uploaded a bunch of images.  All of the smaller images (~<500k) are recognized just fine when I do batch add.  However any of my larger images are not viewable--they actually appear as broken images (the white box with red x). 

Is there a way to remove a size limitation or is there another problem?
