Would I be heavily criticised if I pleaded for a Cats only thread?

I don't like dogs, they, and pictures of them disturb me. I don't want to work through pictures of dogs to get my beloved feline species. I hope it doesn't mean I'm taken as intolerant, and after all,  there is plenty of room for a dog thread.  For that matter, lots of animals deserve a thread, and having one for all only dilutes the pleasure, for me, at least.

Now, about reigning - a thread on this topic, could be contentious, for lots of obvious reasons - we don't want to politicise our royalty. If the topic generally was not political, and I hope this was true, it could be contained in the jokes thread.

I'm willing to start a cats' thread, but maybe someone else could pick up the baton.

I wonder - do images have to be in a specific format, like .png?
Are .gif and .jpg images not accepted?

Also, does the tag material inside the first img code point, as shown in image help, have to be inserted if the image doesn't come from a universally available website?

like this
direct url from webpage/copy image address

I have just noticed the new tool bar above.

The picture in the previous post was from a url, not a stored image file.

trial from stored image  ---
NO. Can't make it work for
{img} image location (computer pathname - host file) image name.jpg{/mg} (using sqbrk)

Question: does the image have to be a url referring to a website? In other words universally available.
How can I make it a url based on a file in my computer?

I should have explained what matzo is for those not familiar with this delicacy.

Take a sheet of armour plate grade steel 2mm thick, about 15mm square.
Drill 1mm diameter holes in a close grid of 10mm each way.
Heat in furnace until surface bubbles.

If you want it buttered, allow several ounces per sheet, allowing for surface roughness.

Or, buy a packet at your local Jewish deli.

ps: it doesn't break at the perforations, or in neat lines.

Enjoy

Trying a link - its a very long description of restoring  an old radio - very interesting only for those interested

OK, I see that when entering the url  there is no formatting info that it is a url, but the URL in [] in the preview mode shows that.

Having opened the picture, I can't see how to close it and return to the message.

EDIT:

I also can't see how to return to the write message pane from a preview.

(1) jackneve is like fishn'chips.  I really wanted to use jayesjay which preserves my name initials without ready identification of my full name.

(2) I don't think I have any relatives in the SE24 area.  One family near Orpington.
