Limit of 100 images uploaded at a time?

Hi all, new to elgg, so please forgive the simple questions...

I have it all installed, and am using hypeGallery 3.1 / hypeFilestore 3.0 / Dropzone 3.0 for my image gallery.

It will not allow me to upload more than 100 images at a time.  Is there a setting or file to edit somewhere to increase this max?

Thanks in advance
