Any common image format should work. However, if you are hosting the image off of CloudyNights, not only must the image be a supported one (like JPG, PNG, GIF, etc) but the URL link to the image must be direct and not through some software access method. You must drill down to the actual image at the host site to get to the image file directly.
For example if you view an image at the host site and the URL looks something like:
then the URL will not be accepted and you will get the message about "You are not allowed to use that image extension on this community."
To use such a remote hosted image, you will have to drill down find the actual image file location on the host without going through the php software layer at the host. Usually, you can click on the image to bring it up and then right click the image and select "Open image in a new tab". (Sometimes, you have to do the first click as a right click and select "Open link in new tab".)
Once the image is open in a tab by itself, the URL should look something like:
which does not go through the php software running on the host system.
A few things to note:
- If you are wishing to link to an image stored on another host to get around the size limit of images on CloudyNights, please don't do that. Instead, copy the image to your local system, edit it to fit the CloudyNights image guidelines (less than 1600 px in each dimension and under 500 KB) and then embed the image into the post using the "More Reply Options" button in the lower right of the Reply pane. You can also post the image to your CloudyNights gallery, make it public, and post the link in your post. The CloudyNights Gallery will take care of making sure the image size meets the requirements.
- If you wish to post an image larger than the allowed sizes, you can reduce the size as mentioned above to put in your post as a "teaser" and then also post a link to the full sized image at the host for those who want to see the full resolution version off of CloudyNights.
I hope the instructions above make sense.
PS: This thread may get moved to the CloudyNights Feedback Forum where it makes more sense. (It is not related to Equipment, so the other forum is a better place for it as the Feedback Forum is made for questions about how to use CloudyNights.)
