I want to ad pictures of my trailer but it says image is to large.
You had some pics of your Spyder in your original post, why did you take them out??

You'll hafta edit that post again; upload, attach, and insert any pics you want to see in there as thumbnails, and you can re-add the Spyder pics plus a couple of trailer pics if you wish, but does that mean you're selling both the Spyder AND the trailer? As a package, or individually?? If the latter, maybe 2 Ads/threads would be better?
If you do add pics, please, no more than 6 per post, but you can add more posts, each with 6 pics in it, to this thread.
The 'too large' message simply means that the image file you're trying to add is just too big to attach/too high a definition/the dimensions of the full sized image is too big to put into the file space available for the post - sorta like you're trying to park the Titanic in a speedboat berth in your local marina... it just doesn't fit, so you need a smaller boat, or cos it's a file, you can just shrink your Titanic down a bit until it fits.
To do that, read the Sticky below; use one of the re-sizing methods/tools mentioned to shrink your image files, I think there's one in post #4 & one in post #17; then upload, attach, and
insert your pics as thumbnails iaw the listed directions. If you edit your first post again, and re-insert some pics as thumbnails into that post, the first pic in your first post will appear alongside your Ad/thread in the index listing.
Here's the Sticky:
If you've been trying to add pics/images/attachments without success, then the most likely issues are that you're either not finishing the upload, attach, and insert (as a thumbnail!) process; or your source image/file is simply too large! So for the former, you need to finish the job properly; the latter, either scale it down or re-size it smaller until it will upload.
When you are adding pictures or images to any post you make, regardless of the device or brand of device you may be using, please have the courtesy to all other members/viewers to use the 'Attach...
Good Luck.
