So, How do I get my original photos up on site if they are too big?
Will reducing them in size alter the EXIF in any way ?

EXIF will remain, resize as you done before. Really, what I meant was uploading the original jpg to a holding site, but comparing yours and mine will tell us something. Ed.

When you say "Holding Site"
Do you mean the likes of "Photo Bucket" ??
I am a registered member there !

I do not think that Photobucket will let you download a pic, could he wrong. I use BOX, here, https://www.box.com/personal/ the free version is more than enough. Ed.

Reduce them in size before uploading them. That shouldn't alter any of the important EXIF stuff except the bit about the size.

If you'll include Lightroom in your workflow, you'll be able to export photos at different sizes, with or without an exif. I highly recomend using it.

I could also recommend you try a cloud storage service, like Dropbox or Google Drive. If it's too big to fit here, you can put it there and share the link.
