If you've been trying to add pics/images/attachments without success, then the most likely issue is that your source document is simply too large! 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, please have the courtesy to all other members/viewers to use the 'Attach Files' button below the text entry field to add any links/pics/attachments. This means that your images aren't subject to changes in the rules at your hosting site, but will remain available to all viewers on the Forum for as long as your post remains. If you use the 'Attach files' button, it should allow you to select the image/attachment you want to upload; open it in your draft post, and once you've done that, it should appear in your draft post (or your submitted post if you go that far!) with the word 'Attachment' above it - you REALLY still need to Insert that Attachment into your post; so once you've uploaded your image/attachment, click on the image and an 'Insert' button should show across the top of the displayed image; click on that; and then you'll get 2 options, ALWAYS click on the first option, 'Thumbnails', in order to complete uploading and inserting the pics/files into your post as thumbnails rather than as full-sized images, which some won't be able to see &/or possibly even open!
That way, those who wish to see the full-sized image can click on the thumbnail to expand it; but if you load full-sized images (even if you've resized them to something that looks about the same size as a thumbnail, the platform software still treats it differently!) directly into the post, some potential viewers WILL NOT be able to see them at all, especially those viewing on small screen devices/phones, and many others may need to scroll a little (or a lot!) left/right &/or up/down just to see your image - IF they can even open the thread!!
So if you submit a post with an image/attachment in it &/or any full sized image and you can still see the word 'Attachment' above any pic/image that you've uploaded, then you haven't finished the job and you'll need to go back and finish it properly! Do this by editing your post; locating your cursor in the text where you want to position the image/attachment in your post; then click on the attachment so that it shows 'Insert' emblazoned across the top; click on that word; and then select 'Thumbnail' to complete uploading the attachment as a thumbnail before (re)submitting the post!! If you want to add another Thumbnail, leave a space or preferably something like ' - ' between them so that viewers can tell that there's more than one image/attachment there instead of just one large, solid, block! And please remember to keep the number of pics/images shown in each post to no more than SIX (6) per post - any more will create loading/viewing issues for some potential viewers too! We don't charge by the post, so if you want to show more than 6, you can always add another post to the same thread.
These two things are not a big ask, but they will help more viewers see your posts!
Below is a Thumbnail - click on it to see full size, then click anywhere on the page to return here; or click on the 'X' in the top right corner of the image/attachment screen.

Below is a relatively small but still Full sized image - it has been scaled down to fit/show on most screens, but this is still TOO BIG for some small screen devices/phones, and even a full or re-sized image that appears to be about the same size as a thumbnail on your display may still be treated by the Forum platform as an image that is bigger than this and so may not be viewable by others!

So PLEASE, have the courtesy to consider other members/your potential viewers and Insert all images/attachments as Thumbnails so that everyone has some chance of seeing them &/or even opening the post/thread. Failure to do this may result in your images/attachments being edited/removed; continuing to do fail to insert them as thumbnails may result in them &/or your post being removed without notice. Thank you.
