Hello,
I want to build a profile image uploader using JSF+Icefaces portlet.I am using liferay 6.1.Actually I want to upload a profile picture of fixed size,show preview of the picture after uploading.Previously I used file uploader using Icefaces component.Can anyone give me suggestion or share a link?
Thanks & regards,
Aritra Ghosh

After you upload the image, will you be calling Liferay's UserLocalServiceUtil.updatePortrait(long userId, byte[] bytes) method in order to update the Liferay user profile image?

Thanks Neil for your reply.I can convert an jpg image to byte array.So,the calling of UserLocalServiceUtil.updatePortrait(long userId, byte[] bytes) can be done.But,to show the image again in JSF portlet,should I use h:graphicImage tag?Can you give me a more details.

Neil,FYI I am able to upload the profile picture for a user.This image can be seen from that user's account.But for user creation I am using my own portlet.Eventually I would like to show the image in that custom portlet.

Very sorry about this -- I originally wrote the following text on April 27, 2012 but I must have clicked on the "Save as Draft" button instead of "Publish". -- Neil

If you have Liferay Faces Portal as a dependency in your portlet, then you can do something like this:

<img src="#{liferay.portraitURL['1234']}">

Where 1234 = the value of com.liferay.portal.model.User.getUserId().

Alternatively you can specify a User object in the EL like this:

<ui:repeat value="#{modelBean.users}" var="user">
    <img src="#{liferay.portraitURL['user']}">
</ui:repeat>

I have found success using getPortraitId() instead of getUserId()

<ice:graphicimage value="#{not empty bean.portraitIdValue ? liferay.portraitURL[bean.portraitIdValue] : '/documents/10180/path to broken image graphic'}" />

			if (cellUserList[col] != null) {
				User cellUser = cellUserList[col];

				return cellUser.getPortraitId();

I use the expression to evaluate value of bean.portraitIdValue. If empty, replace with broken image graphic.

Hi, I'm experiencing the same issue. Have you solved the problem?
