Welcome aboard Monk/Bob.
When it comes to pics, check out this thread, the first post & the listed directions in particular - it's about posting pics/images as thumbnails; and if you check out the links in posts #17 & I think #20 I reckon you'll find some help in re-sizing your raw images.
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...

And if you head down the Spyder path, you won't necessarily find a little vertigo will stop you - there's quite a few of us here who are sufferers, some with milder forms; others with Meniere's &/or BPPV; some with other nastier conditions; and a few of us with some pretty savage 'acute vestibular disfunctions' caused by various degrees of acquired brain Injuries. But if you can handle things long enough to let yourself get some good saddle time, maybe as much as a couple of thousand miles, you stand a pretty good chance of working out why all tend to carry on so much about the '
Miles of Smiles' that Spyder ryding can bring!
