Fix bug where photos become inaccessible
For some reason occasionally I'll see an image in conversation and tap to view the entire image and it comes up blank. The same thing happens if I use the "media" drop-down on the contact of the conversation to see all the images they've sent. I can see all the thumbnails but some of them just pull up a blank image when I tap on them. Some images are permanently like this and other ones it seems to be a transient state of confusion in the app based on having viewed too many images in a row, after a while it just doesn't want to show any more. I can get around that with a restart. But the thing with the images that are always missing the detail, I wonder if it isn't tied to a database corruption or something somewhere in the system. Sorry I don't know how texting data is really stored so I don't know what to try next to troubleshoot it. I want to say Textra has about a gig of data so maybe it's just more than it can safely handle???
