James, you have to host your pictures on another site, like Flickr for example. Copy the BBcode from the host site to here. Flickr is free and has almost unlimited storage. Let me know if you need more detailed instructions.

This is not about the rocks. RTH needs to do something about the photo problem. Everybody has trouble posting photos. RTH...fix it.

Proboards wants money to host pics and cannot hold a candle to a free service called flicker.com. Learn flickr it's easy and free. Plus you can control your images. Put it on a strange host and they own it.

This is not about the rocks. RTH needs to do something about the photo problem. Everybody has trouble posting photos. RTH...fix it. The problem is not with RTH and not everybody has problems posting photos. If you pay attention when the insert image dialog box opens after you click on the insert image icon you will see that it comes up with http:// already there in the address box. If you copied your image address in it's entirety from where it is hosted and then enter it in without first removing the http:// from the dialog box, the actual address trying to be found is invalid. The web and browsers are not meant to resolve an address that is entered incorrectly. So when you post a picture addy without first removing the http:// that RTH put in there for you, it comes out looking like this address.com which is not a valid way of posting a web address. Also, you can easily put a picture from any site on here by simply right clicking the picture and copying the save image address by clicking on that link. Then once again, make sure that the extra set of http:// is removed before pasting the saved addy in. In my first example I will do it wrong Notice, no picture. Now, the same picture done right It appears as though jamest1961 is uploading his pictures to dropbox which is really a file sharing service to which one must belong. Also, I don't think that photos uploaded/available in dropbox are actually linkable.

From my first attempt at posting pics, I did delete the leading http//, now I have moved some pics to photobucket, and copied and pasted several links, which one of the 6 links provided works the best, and does any further editing of it need to be done, because after looking at what appears, it does not match working examples shown. Test

Let me know if my test worked, 2 identical pictures were added above, it seems as though not using the add pic function and instead pasting the link directly into the dialog area worked.

Test These two pictures look identical from here. They are both way too small. The picture in the original post looks great. I'm guessing that you found this on a Lake Superior beach as Ziggy guessed in your other post. It looks like a beach rounded rock. I've never found datolite, but from reading that I've done, you would find that in mine tailings piles, not on the beach. I spent a couple days looking for some, but came up empty handed. It looks sort of like cauliflower on the outside. The inside is pretty evenly colored. Your rock looks like prehnite (aka U.P. Thomsonite) on basallt. I'm no rock identification expert, but that's what it looks like to me. See the faint eyes? That's what sticks out to me, along with the pastel colors. Prehnite is usually pink and/or green.

Let me know if my test worked, 2 identical pictures were added above, it seems as though not using the add pic function and instead pasting the link directly into the dialog area worked. The pictures show now. When using photo bucket click on the photo you want to link to in Library. When it opens up full size, to the right of the pic are link boxes. Select the second box down. Next to it it says "direct". Left click that link and it will say "copied" in yellow. Now go and paste the address that was copied into the insert image box on the top line, making sure there is only one set of http:// Click the insert image button. Pic will show up in a second or two if not right away. The rock in your photo does not resemble any datolite I've ever seen. Datolite is found in crystalline forms as well as masses of porcelain looking material. The ones up here in Michigan typically have an irregularly shaped and white colored exterior. Some have darker rinds but I've never seen one like yours. Some of them have multi colors inside but most don't. Most have a single colored translucent interior. Did you find it in the U.P. of Michigan? I'm with jugglerguy on the maybe pink prehnite. Excellent find if that's what it turns out to be. Course of action would be get as many usable slabs as you can and cab them to highlight the prehnite features. excellent place for datolite photos and info

The rind looks strange, but not out of the realm of datolite nodules, but the interior looks too grainy. Most of the pieces I have handled have had a buttery smooth porcelain texture as Ziggy said. Still, some have inclusions, particularly near the rind. Are any of those dots metallic copper?

If I had to call that one based only on photos I would call quartzite or chalcedony.
