Resizing photos
Guidelines for pictures
- Format
Pictures can be in .bmp, .tif, .gif, .png, or .jpg format format. - File size
We cannot accept files larger than 10 megabytes. We recommend each file to be less than 150 kilobytes.
Large images take a long time to upload. Using smaller images will reduce the time it takes to create your ad. See our resizing tips below on reducing file size. - Resolution
Pictures should have a minimum resolution of: 72 dpi (dots per inch) for online.
Pictures using a smaller resolution will appear fuzzy when you upload them. - Portrait or landscape?
Trading Post accepts landscape and portrait pictures. Both work well online, but landscape
pictures tend to produce the best results for print ads.
Making changes to your pictures
The following can dramatically increase the effectiveness of your pictures.
- Cropping
To improve the framing of your picture, crop it using a photo editor before you upload it to tradingpost.com.au. - Rotating
Ensure your picture is 'round the right way'. Make it easy for the buyer to see what you're selling by rotating your picture before you insert it into your ad. It's difficult to view a picture that is sideways. - Resizing
Adjust the image size to get the right balance between image quality and optimal download time. See below.

Checking file size
The file size generally appears next to the file name in your computer's directory (e.g. Windows Explorer).
If it doesn't, try:
- right-clicking on the file to display the file properties which should include the file size, or
- hovering your mouse over the file name to get a summary of the file, including its file size, or
- changing the view format of your directory to one that displays the details of your files.
Resizing the picture to reduce file size
- There are two ways to reduce the file size of pictures. You can use either or a combination of both to create a picture with the appropriate file size.
Image size
The original size of many digital photos is often large. Reducing the length and width of your picture can reduce file size without affecting the detail. - Image resolution (quality)
Print quality photos are not needed for online use. You can reduce the quality (and file size) and still create a picture that allows a buyer to view all the detail of the original.
The steps below explain the options for resizing your picture. The process as well as the names of the options may vary depending on the photo editor you use.
