Well, the first is a Geoshitties site; most free servers don't like hotlinking (e.g., linking to an image or flash from another server). The second is a Yahoo Groups file. Depending on the moderator's settings, it may or may not show:
1) Images from adult groups will never show unless you have a Yahoo ID and verify that you're over 18 before looking at the image.
2) Images from groups where the files are restricted to members (and most adult groups, indeed most groups in general are like this) will never show unless you're a member. To avoid spam, moderators can take steps to ensure that they have to approve members, or that you have to be a member (by invitation) before you can even see the start page.
3) Finally, each group has a limited bandwidth. If the bandwidth's expired, a file won't show. Furthermore, other than the filename itself, the URL for a file will change a while after every time it exceeds the allowed bandwidth. This also is used to avoid hotlinking.
So the problem is that you're being a bandwidth whore.
Also, LPSG doesn't translate
to <img></img> anymore either.
