Thanks for your reply but i am using drop-zone to drag & drop images and file-upload is disabled. (please see the attachment)
In that case i would suggest you to write a custom DAM workflow.
If you refer the OOB workflow 'DAM Update Asset' workflow, there you can configure which file types should be allowed. Similarly, you can write custom workflowprocess service to check the type and size of the asset and restrict the uploads accordingly.
Example of creating a custom workflow:- https://helpx.adobe.com/experience-manager/using/creating-custom-aem-workflow-steps.html
// Creating custom AEM workflow steps that send email messages
You can create this for your use-case as well.
