Here are the rules for posting attachments and images on Fieldlines:
New members are not permitted to attach images to posts right away. This is to discourage blatant advertising. The limit goes away after you've made 10 posts.
Currently there are no official size limits to the file that can be attached, but in practice there is not much point in uploading files larger than 1000 pixels across and 1 MB.
Pictures larger than 1000 pixels across or high will be resized automatically when you upload them. This may lead to graininess or blockiness that you don't intend.
It is done to reduce the bandwidth needed to load a page full of pictures, for members that don't have a high bandwidth connection.
If you want to load a big picture, but you're concerned that the scaling will make it unreadable, try resizing it yourself first. If satisfied with that result, upload your resized picture.
Windows Tip: If you use Paint to resize pictures, try to crop first, then make sure to "maintain aspect ratio" before resizing. Old versions of Paint do this very badly or not at all. Use something else. On Windows 7 and later, Paint is better, and can scale pictures by % or by desired pixel size. The JPG it saves is sometimes, strangely, more bytes than the original. Paint does not have good JPG compression, so if you're concerned about image quality, again, "use something else".
Android Tip:The standard Gallery has a basic image editor that allows you to crop but not resize. Open to suggestions for folks who have found a nice image editor for Android.
Web pictures:You can insert pictures from other websites by using the "Insert Image" button (the first on the left over the smileys). People who have image gallery accounts (Adobe, Picasa, Photobucket, etc.) may want to upload their pictures there, and link them in. Most readers will not see a difference when reading your post. When you do this, the image link in your post will look like this:
[img]https://www.website.com/folder/image.jpg[/img]
Use this feature carefully though: if the other website deletes or moves the photo, this image link will be broken. Your readers will no longer see your photo. By uploading it instead, your image will always be available.
These rules are subject to change as the needs of our members change, and as new features are added to the software that runs this forum, if it will benefit our members.
Example:This is what the image attachment features look like:

Some tips on how to use them:
![Image posting guidelines 11132-1](https://www.fieldlines.com/index.php?action=dlattach;topic=149480.0;attach=11132;image)
Basic steps to upload your images:
- Expand the + "Attachments and other options" below the text field
- Click Browse to choose the first file from your computer.
- Place the cursor in the text where you want the image inserted.
- Select Inline or End-of-File.
- Notice that a bit of code was inserted at the cursor.
- The file is actually uploaded after you post your message.
The system only allows 5 images per post. If you want to share lots of pictures, just post 5 at a time and make a new post with more.
If you delete the code for the inline photo, you can manually type it back in - just be careful because computers do exactly what you tell them to do.
When you PREVIEW your post, you won't see your picture uploads right away. They will only be uploaded when you hit POST.
If you chose to link in images from another website, you will see them in the PREVIEW. They will already be sized or resized depending on how big they are.
So far, my tips have only referred to JPG format images. Images in GIF and PNG format are also supported and work just as well.
You can also insert documents such as text files and PDF's. They will appear as links in your text if you want to use them.
By the way, this is the image I was attaching "Inline":
![Image posting guidelines](https://www.fieldlines.com/index.php?action=dlattach;topic=149480.0;attach=11129;image)
And this is what happens to the image I attached by "End-of-Post". There's a horizontal line just below this text and the image(s) come after it.
