You may be able to re-size your photo file on your phone. Most phones have this in the settings somewhere...
But in case yours does not, do a Google Play store search on your phone for "photo resizer". There are a number of free applications that should help you there.
We limit the file size because it is very awkward to post your pictures here, only to find you have to scroll a lot to see the entire image. It takes away from what you wanted to show.
We have a section for posting pictures with som good info as well.
Hope that helps!
