How To: Uploading Files and/or Images

Not open for further replies.



We strongly recommend that members attach files/images using this guide instead of linking to remote resources on other servers. If you simply link to remote files and/or images and their servers change, relocate or even go down the remote file becomes un-viewable/broken which destroys the usefulness of threads.

Who Can Attach Files/Images

Everyone! Every member has the ability to attach files and photos to their post.

Knowing the Different Editors

There are two types of editors at ETO, the Quick Reply Editor (Basic Editor) and the Advanced Editor. They are both very similar and work the same, however the Advanced Editor has more features (like file attachments).

Here is a picture of the basic editor options:

Switching to the Advanced Editor

To upload attachments you need to be on the Advanced Editor. If you are currently viewing the Basic Editor then simply click the "Go Advanced" button.

Uploading Your Files

Now that you are on the Advanced Editor look for the Attachments button (
) and click it. A popup will open (remember to disable all popup blockers - most browsers now have them).

A popup box will have now displayed which allows you to choose the files to upload. So, if the file is located on your computer click "choose File" button and add your file. When you have selected your files click "Upload".

Note: This form allows you to upload 3 files at a time, to add more than 3 files to a post simply repeat the process.

Acceptable File Types

Within the Attachment popup window there is a lists of the allowed filetypes and maximum file size for each.

Recommended Image Types

The image formats JPGs, GIFs and PNGs are all recommended. These types of image are compatible on all computers without any additional software, and 99% of browsers support them (PNGs sometimes don't work on very old browsers). They also use significantly less space than other image types therefore quick to download.

They do slightly differ from one another, here are the pros and cons:
- JPGs are best when the image has a lot of gradients and shading (digital cameras always use JPGs)
- GIFs are best when the image has a lot of text and straight lines (like schematics)
- PNGs are a new format that surpass the quality of GIFs but are not compatible in very old browsers.
