Hi prd,
Firstly please make sure the file has actually uploaded before clicking "all done". You should get a filename (I think) and a thumbnail of the image when the upload has finished.
Don't own a macbook but here's some info, speculations and perhaps pointers that may help.
A couple of things can contribute to apparently failed uploads:
1) the image is actually quite large
2) the 'upload' direction of your internet connection can be painfully slow.
What happens is most of us download info- text, pics, videos, etc. Which is data heavy. But most of what we send are keystrokes asking for that info, which is a very small amount of data itself. So what the internet providers companies do is say, okay: People download megabytes (gigabytes nowadays) but only upload maybe kilobytes (1000s of times less than the downloads). So we'll configure our connection for that.
This especially applies for cheaper connections (like I have) or in the country.
It's like an 8 lane highway with 7 lanes coming to you and only 1 going away. You can receive data quick, but sending it can be a bottleneck.
Now that bottleneck occurs when you try to upload pictures- which is usually what you're downloading. Instead of 7 lanes you only have 1 so the traffic is slower.
'Nuff of the handwavy explanation. It could also be that there is an issue with upload. But let's perhaps try something first.
Before you try to upload the image, perhaps try to reduce the file size or resolution. I'm not sure how to do that on a Mac so perhaps someone more knowledgeable can weigh in?
Basically, the odk site will reduce the resolution anyway so you might as well do it. By reducing resolution you reduce the size of the file to send and hence the time taken. Sometimes programs are clever, for example if you try to email an image it will often reduce the size for you automatically.
But that's not likely here I suspect because of the way the site operates. I suggest you may be able to export or "save as" a photo from whatever program/app you use and in doing so some options may allow you to reduce the size/resolution/quality. Once that's done, try uploading the newly saved, reduced file.
Cropping the photo to the relevant area is another way of reducing file size.
And try just one file first.
I hope this helps in some way! I have exactly the same issue with my photos/upload speeds. Every photo I upload has been reduced in size for this reason.
