How to increase the Thumbnail photo size.

yes.  I still don't know how to increase the size of the thumbnail photos.

Yes, some better flexibility with thumbnails and maybe add tiles for videos to see quick previews as we mouse over.  But, until then.  Use your browser zoom +  tab key to increase the size of the entire page. I've tried it, it's not perfect at all but it gets part of the job done pretty well.  A better alternative, again not perfect, is to install a magnifying app that will make the thumbnail larger, again as its "moused" over.  They have some pretty cool ones where you can set an exact x/y axis although I haven't seen one that can do them in batch.

Drop box has a a forum section (or used to, I haven't looked in here for awhile) where you can give constructive ideas for improvement.  Personally, I think the big planners need to slow down a bit on the supposed "massive growth of subscribers", and sit back and modernize this place a bit. Many will disagree but for my use there hasn't been any significant upgrade in the look, or the function tabs since it was first developed.  I'm talking significant.  It's tweaked here and there but IMHO I think it lacks some pizazz, imagination and more functionality on the primary pages without having to search through the entire site.  That's my 2C.  Hope I helped somebody.  Geesh,  asked back in February and they are supposed to have millions of subscribers?  Hum  Hm. What's up with that? Never mind, I could care less. Have a good day. Rob

Fascinating, that after YEARS of people, both free and paid Dropbox users, continue to complain about a simple issue with the miniscule picture icons, and THERE IS NO ANSWER FROM ANYONE AT DROPBOX, AND NO FIX. Really?! What an insult. 

That's why I have chosen to spend my money elsewhere.

Well, it's too bad about this but take a look at the list of improvements and requests people have made over the years.  DB must prioritize and it's something I certainly would not take personally, and leave, unless it's such a high priority in what you do. Thankfully there is a plethora of choices.

I have this problem, too, of weensy thumbnail icons. And I want to delete photos no longer needed.  

this is pathetic

How do I increase the thumbnail size for pictures in my camera uploads folder? The current tiny thumbnails are totally useless. This is such an elementary feature that there must be a simple setting somewhere - can anyone point me towards where it is please? Thanks in advance

This is not possible John. 

The only suggestion I have is to increase the zoom on your browser.

It turns out that the thumbnails are 32 x 32 pixels. Seriously?!? What planet are dropbox on that they think it's acceptable to display such pathetic thumbnails? Wow!
