Help with album photos - VB4

[wcpmrj]

I've been up for 18 hours trying to figure out the limitations of photo albums. As usual vbulletin+google = poor results. As does searching this forum for answers. I'm in shock I'm the only one asking these questions, but hopeful that it's because I'm just over looking something extremely simple.

1) Why when I upload certain photos does a white question mark pop up, blocking the image and preventing me from posting it "inline" on my posts?

2) Is there any way at all to use the photos in your "Home" folder (where they sit when you upload the attachments/photos in your album) when on a smartphone? Currently I can only see the "drag and drop" option, which I can't do on a smart phone. I really can't just check off the ones I want? Or hard button select them? Is drag and drop REALLY the only option?

*update*

1) I found out that the only photos, regardless of size or shape, that will actually appear in VB are .PNG ang .GIF files. JPEG, JPG, and BMP will not. Of course iPhone photos are .JPG.
