Not followed this tapatalk discussion but if the forum max image size is 2MB, then its 2MB. Tapatalk will have to compress the image or upload it somewhere else (for example, Jassy image in the post above is hosted by tapatalk servers).
I just upload to imgur.com for things over 2MB (which is most images I take). (I hate tapatalk as an app). For sake of talking about capacity, my phone has 128GB of storage, so that can hold 64,000 images on this forum.
I understand needing image file size limits, but in 2018 with how cheap storage is and how many MPs cameras have, 2 MB is not a whole lot.
.. rant over and back to cars..
The vodooo looking super nice in that pic!
