I could not find a feature for this in the attachment macro, so I've created a new improvement for you: https://jira.atlassian.com/browse/CONF-29082
I suggest to vote and add your comment to the ticket to increase the chances to be implemented in the future. I hope this helps! :)
I've created a macro with a drop-down list of fileType to Exclude. If you want, add more type of files in the "enumValues" part of the parameter definition:
## Macro title: Exclude File Type Upload Area
## Macro has a body: N
## Developed by: Name
## Date created: dd/mm/yyyy
## @param fileTypeExc:title=File Type to Exclude|type=enum|enumValues=png,jpeg,bmp,xlsx,xls,docx,doc,pptx,ppt,zip,rar,pdf|default=png|desc=Select type of file to exclude (ask the Confluence administrator, if you want to exclude more than one type of files)
<p><ac:macro ac:name="attachments"><ac:parameter ac:name="patterns">.*.[^($paramfileTypeExc)]$</ac:parameter></ac:macro></p>
