Understand Image Field | Zoho Creator Help

Understand image field

  1. When accessed via your iOS devices' browsers, you can upload images and attach image URLs but you cannot capture them via the image field. This is because media objects are not supported by iOS.
  1. When accessed via Safari browser, you can upload images and attach image URLs but you cannot capture them via the image field. This is because media objects are not completely supported in Safari.

The image field enables your users to submit an image through your form. They can either take a photo or upload one. The following is how an image field looks on a form:

  • When a user accesses from a web browser:

  • When a user accesses from a phone or tablet:

Note: The files that you upload will be scanned for any virus before form submission. You will have to upload a different file if the uploaded file contains a virus.

Size limits

  • When a user accesses from a web browser and uploads an image from the device's local storage, the image field can accept an image up to 10 MB
  • When a user accesses from an iPhone or iPad device and uploads an image from the device's local storage, the image field can accept an image up to 5 MB
  • When a user accesses from an Android device and uploads an image from the device's local storage, the image field can accept an image up to 5 MB

The images that your users submit through your form are stored in your account and are counted towards your account’s total storage limit. Visit your account's  usage details  page to view its current storage details.

Uploaded image's name

When your users upload an image to this field, the image's name is set in the following format:

  • The image's name is prepended by an underscore (_) and a system-generated number that uniquely identifies that image in your account
  • The image's name will automatically be trimmed when it exceeds 150 characters
  • Whitespaces and other special characters, excepting hyphens (-), will be replaced by an underscore (_).

  2. If the  Enable photo gallery  field property is enabled, tap  Take Photo . This will launch the device's camera.
  3. If the  Allow to Switch Camera  field property is enabled, you will be able to switch between the device's cameras.
  4. Take a photo by tapping the  Shutter  button. You will get to preview the image you took.
  5. Tap  Use Photo  at the bottom-right corner of the screen, or tap  Retake  at the bottom-left corner to retake the image.

Field properties

You can also perform the following customizations for the user experience of the image field on your form:

Downloading images

URL to download an image

Note : This URL works for images that are either uploaded from local storage or captured using the device's camera

An image stored in the image field can be downloaded using the following URL:



  • domain  will be DC specific—for example, you'll need to use  creatorexport.zoho.com  if your account is in Zoho's US data center, and  creatorexport.zoho.eu  if in the EU data center.
  • account_owner_name  contains the user name of the Creator application's account owner and the link name of the application.
  • reportLinkName  is the link name of the report where the corresponding image field is displayed. (To know the report link name, click on  Report Settings ->Summary  from the edit mode of the report to get the reportLinkName).
  • fieldLinkName  is the  link name  of the corresponding image field. 
  • imageName  is the corresponding image's name.  Learn more

For example, imagine that you've built an application named  Zylker Automobile Service . In this application, you have created a form named  Emergency service request , where users can capture the picture of their damaged vehicle, add a description for the image and submit the form. When you access the  Emergency service request  report, you may want to download the images. To do this, you can configure a custom action in your report, such that when you click the button  Download image , the image gets downloaded. This custom action has the above URL format constructed as follows:

tempFilename = input.<fieldLinkName>.getsuffix("image/");
tempFileName = tempFileName.getprefix("\" lowqual");
openURL = (" https://creatorexport.zoho.com" + zoho.appuri + "<reportLinkName>/<fieldLinkName>/download/" + tempFileName, “window type”); 


  • tempFileName  is a variable that stores the filename of each image stored in the image field
  • getsuffix() returns all the characters which follow the first occurrence of searchString in the string.  Learn more
  • getprefix() returns all the characters which precede the first occurrence of searchString in the string.  Learn more
  • zoho.appuri  returns the application details in the format:
  • The  openUrl  Deluge task is used to redirect the user to the specified URL. This URL can be opened in the same window, new window, parent window, popup window, or iframe

Now, when you access the  Emergency service request report,  you can see the  View image  button:

In the above image, Megan is the <account_user_name> and zylker-automobile-service is the <application_link_name>

Tip: This URL format can be used to download files from the file upload, image, audio, video and signature fields

Download images in bulk using the file download tool

Note :
  1. The file download tool supports downloading of files from file upload, image, and signature fields as of now. You cannot download the files if these fields are in a subform inside the parent form.
  2. This tool is currently only supported for Windows.
  3. Ensure that you have ten or fewer authtokens in your accounts.zoho.com to avoid any username or password-related errors
