Once you've completely fallen for... Model(s) X you can upload an iStripper photo of her from the photo set you have downloaded. Click the 'Add image.' picture icon below the box you type in.
Or in the app (not sure about via the web site) you can ***** and drop a picture, or several at once, to the text box.
Note, there is a limit on the size of an image file that can be posted so you may have to reduce that, e.g. by converting from a .png to a jpg. Also what is then made available to others to download may be of a lower resolution than the image you think you uploaded.
What is the word limit by the way? Has to be crazy long from what I've seen.
At least 5000 characters (I've just checked that long ago I posted one that was almost 6000 characters long). But it's less than 8000 - I recently had to split a post that would have been 7921 characters long. The limits may have changed but the longest of the parts that I split it into was almost 5000 characters (I did not count end of line characters, but they should be included so maybe the upper limit is a little over 8000)
If you do make an overlong post it just gets truncated without any warning so it is easy to miss seeing that such a post is incomplete. Very annoying if you typed it straight into the app as there is no way to retrieve the lost text, so if you want to make a long post prepare it in a text editor and keep it until the post is completed. This is a sensible precaution anyway for any but a short post (doubly so if you are editing a post) and it allows you to spellcheck the text.
Note, some single visible characters (called glyphs), notably emoticons but also some punctuation and non-latin alphabetics, require multiple characters to encode a single glyph. Using any of the formatting features such as bold, quote, code, or introducing links to other posts will also contribute to the character count - but normally this will be a small contribution amounting to a few characters of overhead for each change in the formatting.
